+ The resource manager can lookup assets by name and classID.
+
+ An resource file is generated with the editor. And is shipped with unity.
+ It provides the most basic assets necessary to run unity.
+ Eg. some shaders, some textures for lighting
+
+ If you want to add a new resource to the ResourceManager:
+ - Call RegisterResource inside InitializeResources (Use a unique id and never reuse an id)
+ - Open a project with the resources you want to add
+ All resources have to be placed inside a "Assets/DefaultResources"
+ - When you have assembled all the resources. Use BuildResources from the main menu.
+ This will Install them in the right folder and also
+ invoke installframeworks so it is installed in all versions of the editor
